y(3)=-108
Answer:
x = 0, x = 2/3
Step-by-step explanation:
x / 4 = x² / (x + 2)
x = 4x² / (x + 2)
x * (x + 2) = 4x²
x² + 2x = 4x²
3x² - 2x = 0
x(3x - 2) = 0
x = 0, x = 2/3

We are given with the expression <span>tan2x / x</span> and asked to evaluate the expression to limit as theta approaches zero. In this case, we substitute first zero. The answer is zero over zero. This is indeterminate so we derive the terms accdg to L'hopital's rule. The derivative is 2 sec^2 2x/1. cos 2x is 1 so is sec^2 2x. Hence the answer is 2.
The time will it take the runners to cover 1/A mile
t= 5904.6 sec
<h3>What time will it take the runners to cover 1/A mile?</h3>
Joel takes 63 sec for 14-mile long track
speed of joel
Jason takes 57 \mathrm{sec} for 14 mi track
so Jason's speed is
therefore
if both start from the same spot in opposite direction then
where x is the distance covered by Joel
then
time required
